) to create
gas for sulfonation reactions, using steam-jacketed tanks for heating and melting. The system ensures a stable, clean, and measured flow of molten sulfur to the sulfur burner.
Key Aspects of Sulfur Melting in Sulphonation Plants:
- Melting Process: Solid sulfur is fed into a melting tank, which often mixes fresh solid sulfur with already melted liquid sulfur, keeping it heated with steam coils or jackets above the melting point.
- Insulation: All pipelines and tanks are steam-jacketed to keep the sulfur in a liquid state during transfer to prevent clogging, as sulfur solidifies when cooled.
- Filtration: A liquid sulfur filter is frequently used to remove impurities/solid particles before the melt goes to the burner to prevent clogging nozzles and ensure quality.
- Dosing: A submerged gear pump and a flow meter (often mass flow) precisely control the amount of liquid sulfur fed into the burner for optimal combustion.
- Heat Recovery: Modern plants often use heat from the sulfur burner (via a fire-tube boiler) to create the steam required for the melting tank.
Common Equipment Components:
- : Usually steam-heated.
- : Steam-jacketed, often a submerged gear pump.
- : Removes impurities.
- : Insulated tank for intermediate storage before the burner.
This setup is crucial for creating a clean and consistent sulfur dioxide (
) gas, which is then converted into sulfur trioxide (
) for the production of surfactants.

What happens if you melt sulfur?
However, when heated for longer, liquid sulfur becomes reddish-brown and viscous due to the formation of much longer molecular chains . If this substance is cooled very quickly, its molecular chains don't have time to break down. As a result, the substance turns into plastic sulfur and becomes malleable, like clay.

Why can't you touch sulfur?
Handling or touching sulfur without gloves may cause skin irritation. People with asthma or other respiratory problems may be more sensitive. Symptoms may not show up until a few hours after exposure. If someone has been exposed, contact a Poison Control Center at 800-222-1222.
